"D" is much worse than an underrun, especially at such low sampling rates; it means "Dropped Network packet". Something is very very wrong with your networking. How are you connecting your USRP to your PC? What is your Network card?

Best regards,

Hello Marcus,

Thank you again for your help last time. I'm using both  LFTX daughterboard and LFRX daughterboard 0-30 Mhz on top of the N210. Also I reduced the sampling rate to a rate that the USRP can support. I removed the throttle and the BER block reading was 0.112. To me 11% lose considered high at distance of 10cm. I don't see any overrun sign on the console but "D" and it fixed after assigning 200K sample rate. i know the input for the modulation is packet and output of demod is bytes to get bits I have to unpack them but and this what I did but One more question is the input to the BER block equal? am I missing to adjust important parameter?  

Thank you.
